If it is KP, I doubt it's diet related. KP's genetic. Most references I read say it's common on the back of arms and thighs. Not one mentioned hands. Most said that KP is itchy, too. Have you been exposed to a new cleaning product, or bought a new hand soap recently? Have you done any painting... or a new hobby? Just looking for something that might cause a contact dermatitis. Those mostly itch, though. Have you consider going to a dermatologist? Tril
